DENTAL FILM PACK on PACKET.

Application filed January 14, 1921.

vent a child or a nervous patient from swallowing the packet containingthe film.

In making X-ray pictures of the teeth, it has been found from practicalexperience that the smaller the dental-film packet used the greater theconvenience to the doctor and the patient, providing that the packet issufficiently large to permit the X-raying of one tooth; Such a smallpacket might, however, be swallowed by a nervous patient ora child,the'result of which would probably prove a serious detriment. It hasbeen found, also, that, in a great many instances, patients are more orless nervous and that there is considerable difficulty in getting adental-film packet held in the correct position. It is the universalcustom for the patient to hold the packet in position with his or herown finger, and as the packetsheretofore used possess no guide of anykind, the patient frequently allows the packet to slip out of position,which fact is not discovered until the film is developed.

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts whereever they occur.

Figure 1. is a front elevation of a commercial dental film packembodying the invention;

Figure 2 is a side ele ation of the film pack, and Figures 3 and 4 are,respectively, front and side elevations'of a modification of theinvention.

Referring to the drawing, this invention consists of a dental-filmpacket 1 of small size, and for the purposes of the present inventionpreferably of a rectangular or ob; long formation, having its oppositecorners rounded off in a manner to not in any way injure the mouth orgums of the user when inserted into operative position, and to one sideor one end of which is attached or IV. BUCK,

Serial No. 437,345.

formed a right-angled projection :2, which projection, when formedseparately thereof, may be made of cork, rubber, wood, or any othersuitable material, and, in any'case,'is designed to be yieldable orcompressible under the gripping action of the teeth of a patient,whereby any tendency for accidental displacement of the film packet fromcorrect position is reduced to a minimum.

The projection may be molded integral with the packet or attachedthereto by an adhesive or the like. This projection will rest on thecrown of the tooth and act as a guide to enable the patient to hold thesame in the proper position, and it, also, increases'the size andthickness of the packet in such a manner as to overcome the probabilityof the patients swallowing the packet, which is of special importance inX-raying teeth.

The projection 2 is preferably provided with rounded corners .3 and 4;,and may extend clear across the packet to which it is attached or onlypart way, but the principal feature of this invention is a dental-filmpacket possessing a permanent projection extending at approximately aright angle to the packet.

In the drawing, the projection 2 is shown as being preferablycoextensive with one of the marginal edges of the packet 1, and itsopposite ends rounded off to conform to the rounded corners of thelatter complemental thereto, whereby to further prevent injury to themouth or gums of the user.

Likewise, the projection 2 is shown flush with the margin of the packet1, but may, if desired, be merely adjacent thereto.

In its preferred embodiment as shown, the device is in the form of acommercial dental film pack 1, of the rectangular or oblong shape ashereinbefore mentioned, with the extension 2, preferably int-he formhesive or other means to form a unitary article of manufacture andextended across the upper or outer face of the film pack 1 at or nearone of the marginal edges thereof, whereby, when the extension 2 isengaged on or otherwise gripped between the teeth of a person, the filmpack 1 will have its front face disposed directly in rear of either oneor more, depending upon its area or size, of the teeth of the upper orlower sets of the same, and will remain in such position .of-a bead orrib, attached thereto by adas long as the person maintains a bite on theextension.

In Figures 1 and 2 the projection 2 has been shown as engaged with oneend of the packet. However, if desired, this projection may be arrangedto lie parallel with the lateral margins of the packet as shown in Figs.3 and at of the drawings.

Having thus described this invention, I hereby reserve the benefit ofall changes in form, arrangement, order, or use of parts, as it isevident that many minor changes may be made therein without departingfrom the spirit of" this invention or the scope of the following claims.

I claim:

1, A new article of manufacture consisting of a photographic film packprovided at one extreme edge with a laterally projecting flange.

2. A new article of manufacture consisting of a photographic film packprovided at one extreme edge with a laterally projecting flange, theflange extending the entire length of said edge and the corners of thepack and ends of the flange being correspondingly rounded.

In testimony whereof I hereunto afiix my signature.

ARTHUR W. BUCK.
